Micromachine for treating bilateral vocal cords paralysis and system of micromachine for treating bilateral vocal cords paralysis

Abstract

The invention relates to a micromachine for treating bilateral vocal cords paralysis. The micromachine is of an implantation instrument which at least comprises a left lever part arranged in the left side vocal muscle, a right lever part arranged in the right side vocal muscle, a rotating shaft seat configured to be a connecting base of one end of the left lever part and one end of the right lever part and a micro-drive apparatus driving the left lever part and the right lever part to rotate to realize close and open movements of the left lever part and the right lever part, and the left lever part and the right lever part are hinged by taking the shaft seat as a base point. The micromachine drives the vocal cords to open and close, uncontrollability of electrical stimulation due to different muscle functions or states is avoided, and loss of electrical stimulation due to atrophy of the vocal cords is avoided.

Description

technical field [0001] The present invention relates to medical equipment technology, specifically a micro-machine for treating bilateral vocal cord paralysis and a system for applying the micro-machine. Background technique [0002] Many reasons in life can cause bilateral vocal cord movement disorders, including idiopathic bilateral vocal cord paralysis, bilateral vocal cord paralysis caused by tumors, surgery, trauma, etc. After bilateral vocal cord paralysis, the patient's vocal cords cannot be abducted normally, but most of them can maintain a certain degree of adduction function, which leads to the inability of the glottis to open when the patient breathes, resulting in dyspnea, which affects the patient's exercise and life, and in severe cases can lead to The patient suffocates to death. Due to the existence of the adduction function, the patient's vocal function is not greatly affected. Generally, the therapeutic methods adopted in clinic are partial resection of v...

AI Technical Summary

Problems solved by technology

[0004] However, the traditional stimulation of muscles and the above-mentioned method of stimulating the cricoarytenoid posterior muscle make the electrical stimulation effect uncontrollable due to different muscle functions or states, and at the same time cause loss of electrical stimulation function caused by vocal cord muscle atrophy
